(+)-Niguldipine hydrochloride  (Synonyms: (S)-Niguldipine hydrochloride)

(+)-Niguldipine hydrochloride is an antagonist for calcium channel. (+)-Niguldipine hydrochloride produces vasodilation by blocking calcium channels and reducing the transmembrane influx of calcium ions. (+)-Niguldipine hydrochloride inhibits U-46619 (HY-108566)-induced coronary vasoconstriction in guinea pig Langendorff heart with pID₅₀ of 11.37, binds to calcium channel on guinea pig skeletal muscle membrane with K_i of 9.75, and lowers the blood pressure in spontaneously hypertensive rat with pED₃₀ of 7.1. (+)-Niguldipine hydrochloride ameliorates cardiovascular diseases such as hypertension, angina pectoris and arrhythmias^[1].
